You operate a small non profit that provides subsidized tutoring services to high school students in underserved areas. Approximately $60\%$ of the discount costs of tutoring are your clients while approximately $20\%$ are billed directly to the students. The remainder that is not covered by program operating revenues must be covered out of general operating funds provided by foundations and individual donations.

You are asked to build a cash budget for program revenues.

Assume the following:

Of the expenses billed directly to schools, two thirds are paid in the month following delivery of service, with the remainder paid the next month $($that is two months following delivery of services$).$

Of the expenses billed to families, $80\%$ are paid in the month following delivery of service; $10\%$ are paid the following month; and $10\%$ are not paid at all.

In January, February, and March, program expenditures on services provided are $$30,000$; $$36,000,$ and $$27,000$ respectively.

Given the information provided regarding payment schedules, what will the cash budget show as operating revenues for the month of March? a$)$ $$32,160,$ b$)$ $$26,760,$ c$)$$$21,600,$ d$)$$$27,000$
